#49 The Doomsday clock has ticked another minute closer to midnight on the back of global uncertainty on how to deal with the threats of nuclear weapons and climate change.

"It is now five minutes to midnight," said Allison Macfarlane, chair of the Bulletin of Atomic Scientists (BAS), which created the clock in 1947 as a barometer of how close the world is to an apocalyptic end.

Increasing nuclear tensions, refusal to engage in global action on climate change, and a growing tendency to reject science when it comes to major world concerns were cited as key reasons for the latest tick on the clock.
